These are my observations, however I haven't fact checked.
Most new chargers are 150kW I believe, however many of the older ones are 50kW. Tesla also has quite a few superchargers, where some (or maybe all?) of their chargers are opened up for other cars. (In Europe, or at least Norway, Tesla doesn't use their own proprietary plug)
There are comparatively very few public AC chargers, but many (most?) people have one at home, since charging directly from the socket is legally regarded as a backup solution. Most people charge at home and use the DC chargers for longer trips.
I believe the price per kW for DC charging is about 6 times more expensive than charging at home.
